IMPROVEMENT IN SASH-HOLDERS FOR CAR-WINDOWS AND BLINDS.

- Specification forming part of Letters Patent No. 123,577, datedFebruary 13, 1872.

To all whom it may concern:

Be it known that 1, CHARLES P. MIXER, of the city and county ofiVorcester and Uommonwea-lth of Massachusetts, have invented certain newand useful Improvements in Holders for Gar-VVindows and Blinds and forother purposes; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming part of this specification, and in which-Figure 1 represents a front view of so much of a section of awindow-frame and its jamb as is necessary to illustrate my improvements.Fig. 2 represents an edge view of the windowframe or blind with theholder in position and Pi g. 3 represents a longitudinal central sectionon line A B, Fig. 2. v

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail. v

The nature of my invention consists in the combination, with the blindor sash-frame and the jamb, of a holding device, constructed andoperating as hereafter explained.

In the drawing, A represents one side of the sash or blind-frame, whichis recessed or cut out, as shown at a, with two holes, 11 b, bored inthe edge of the frame to receive the spiral spings o c A center conicalhole, (Z, is also bored in the edge of the frameto receive the conicalsocket e of the metallic frictionplate B, the-latter being made with itscenter depressed or curved in, as shown at f, while its ends projectout, as shown at g g. The frictionplate B is held in position by meansof a screw, 0, which is passed through the central hole h of the conicalsocket e in the plate B, and screwed into the edge of the sash orblindframe, as indicated in the drawing. Screw 0 should be turned in sothat its head will be within the outer edge 2 of the sash or blindframe.D represents the jamb of the sash or blind-frame.

It will be seen from the foregoing description, that when the holdingdevice is secured to the sash or blind-frame, and the latter is placedin position, as shown at Fig. 1, the outer sides of the ends 9 g of theholding or friction-plate B will be pressed by the spiral springs c. 0against the inner edge of the jamb of the window or blind-frame, asindicated in Fig. 1, the friction between the holding-plate and the edge.of the jamb depending upon the power of the springs employed forforcing out the holding-plate B. As the friction and holding-plate B isforced in, its socket e enters the recess 61 formed in the sash orblind-frame, while, by means of the depression f, the friction isapplied at each end only just opposite the spiral springs c 0. The screw0, which is held in the socket e, prevents any longitudinal movement ofthe friction-plate, which would tend to cramp or jam it in the recess inwhich it is held, 'while at the same time the conical or flaring form ofthe socket allows the plate to tilt so as to conform readilyto theposition of the sashframe or jamb. The springs c 0,

frame, and also into the sockets l" 1 of the friction and holdin g-plate, prevent the latter from turning as it is moved up and down with thesash or blind.

By the use of my holding device, combined in the manner shownanddescribed, a carwindow or blind can be retained at any desiredelevation, thus dispensing with the numerous objectionable and annoyingfastenin gs My holding device is both simple in construction and inoperation, and not liable to be injuriously afiected by dust or thecontracthe frame A, jamb D, and casing E are made.

I have shown and described my device as applied to a car-window orblind; but it will be apparent to those skilled in the art that it canbe employed for other and analogous purposes with good effect.

Having described my improvements in holders for car-windows and blindsand for other purposes, what I claim therein as new and of my invention,and desire to secure by Letters Patent, is-' A sash-holder, composed ofth e metallic plate B, provided with sockets 1 1 and e and depression f,in combination with screw (3 and springs c c, said parts beingconstructed and arranged for joint operation as shown and set forth.
